Re: AR Vs Tortoise to power frog
I've drawn a diagram of my railroad's yard and reversing tracks. I looked for where to post them to the group, but didn't find the place. Can someone point me to it? -- Don Weigt Connecticut

Re: AR Vs Tortoise to power frog
DonV, I don't have a decent way to post my track diagram. It would need to be hand drawn, then scanned. Back in the '90s I had more CAD capability than I do now. Moving on in my Microsoft computer OS

Re: AR Vs Tortoise to power frog
And if you switch the main - you may run into problems with another train being 'across' the gaps and preventing the auto-reverser from working. Bottom line - reversing is/can be a "tricky topic".?

Re: AR Vs Tortoise to power frog
Post a diagram of your track plan or remind us of the link if you have already done so. Then me and others might have other suggestions. DonV

Re: AR Vs Tortoise to power frog
DonV, I've thought about switching the mainline "polarity" instead of the storage tracks, but concluded it has no overall advantage, given the other connections in the yard to the tracks that would

Re: Need advice on wiring a cross-over and wye junction
Check out dccwiki.com and. Search for crossings to determine if the crossing you have is a dead frog or other type. Verify with an ohmmeter on the bench. A dead frog type would be the easiest to work

Re: Need advice on wiring a cross-over and wye junction
Tim R may be correct. If there are no rail connections between the right and left parts of the crossing X ... Wire tracks A, B and D together with the upper fixed polarity feed tracks from the

Re: AR Vs Tortoise to power frog
Jim, I'm on G-Scale, and wouldn't dream of getting rid of the keep-alives. Worth their weight in gold. A drawback that's not so easy to see is that on track dirty enough to make the keep-alives do

Re: AR Vs Tortoise to power frog
Don, Wise decision - in my opinion.? And you know what - operators other than your grandson will appreciate it/depend upon it as well.? Because using a DCC auto reverser means that you don't have to

Re: AR Vs Tortoise to power frog
Paul, I agree with you about its being a "band aid" - and I still install keep alives in almost all locos.? The locos?simply run better in all situations. Properly maintained locos and track is?the

Re: Need advice on wiring a cross-over and wye junction
David; The only place where an AR is needed on this arrangement is on the turntable bridge, and you need something there anyway. I'm not sure how an Atlas turntable is wired, so you may need to gap

Re: AR Vs Tortoise to power frog
Don; I'll soon have a situation similar to yours. A double ended staging yard where one end represents Charlotte for southbound trains, and the other Winston-Salem for northbounds. Both of these

Re: AR Vs Tortoise to power frog
Don W. Have you considered making the storage tracks constant polarity and the mainline (or at least part of it) the AR section? DonV

Re: AR Vs Tortoise to power frog
Tim, Like you, I've never had AR circuits on my railroad. Unlike you, I probably will add some soon. My railroad has a reversing loop that's five blocks long, totaling about 60 feet in length, with

Re: AR Vs Tortoise to power frog
Yep to all of that. I use the TCS KA 1s or 2s exclusively because they give me the shortest time. it's still more than I need. When I do an install, I always make sure the client knows what he's

Re: AR Vs Tortoise to power frog
Tom, Yes, they both "work" ... that's the problem.? By the time the AR has thrown the turnout (due to detecting the approach of the loco - a short) the keep alive has run the loco far enough to

Re: Need advice on wiring a cross-over and wye junction
Thanks, Blair. Beyond the small 'Y' is a very short space and then a double crossover begins which is managed by 2 MRC auto-reversers. But, I'll put up the diagram, as is, unless you think I need to

David, You'll have to post the picture to the photos area here.? I saw your post on the Digitrax list.? You have two options: 1) The stretch from the crossover to the small 'y' could be fed via an
